It also made head coach Paul Johnson happy for one big reason.Johnson, as many know, has personal issues with Louisville defensive coordinator Brian VanGorder. So much so that it’s fair to say that Johnson had no problem hanging 66 points on his adversary – including 35 points in thes second half. The Yellow Jackets won 66-31.Why is there so much beef between the two? Basically, Johnson was the head coach from Georgia Southern from 1997 to 2001 and ran his option system successfully. When he left, Mike Sewak took over and kept the system. But after 2005, Sewak was replaced with VanGorder, who made a comment about bringing the program into the “21st century” on offense.VanGorder lasted one season at Georgia Southern and posted a 3-8 record. Ever since, Johnson has had it out for him.As the old story goes (via @DavidHaleESPN):Brian VanGorder: Let’s bring Paul Johnson’s offense to the 21st Century.Paul Johnson: I want to beat the hell out of Brian VanGorder.(Johnson’s team currently has 66 points on VanGorder’s.) pic.twitter.com/NPTAtQ9Zj6— Matt Fortuna (@Matt_Fortuna) October 6, 2018Here’s a quote from Roger Inman, who coached with Johnson back at Georgia Southern. Via USA Today:“VanGorder had made some comments that he didn’t think too highly of the offense, and Paul called me up and said, ‘I need to talk to (athletics director) Sam (Baker) and get Georgia Southern on the schedule,’” Inman said. “I said, ‘Why do you want to play us?’ And he said, ‘Because I want to beat the hell out of Brian VanGorder.’ “VanGorder has worked for dozens of programs. He was fired as defensive coordinator at Notre Dame in 2016 but served as an assistant at both Georgia and Oklahoma State since. His current stint as defensive coordinator at Louisville is not going well.Georgia Tech put up 554 yards of offense on the Cardinals Friday night – with 542 of them coming on the ground. That likely wasn’t a coincidence.
